  WRAP operation fix for MyEID driver (T0 protocol)

apdu.le must be greater than 0, because we expect a result (wrapped key).

Although the value 0 seems to be correct in this case (function
sc_apdu2bytes() generates the correct field 'Le'), the operation fails in
sc_get_response() where Le == 0 generates only SW.

>From the point of view of the sc_get_response() function, apdu.le here
represents the value "Ne" (see ISO 7816-3 section 12.1.2), and thus apdu.le
cannot be 0 in this case.

Fixes #2694
